Abstract
The process of rolling step-shaft was simulated with the help of the FEM (Finite-Element Model) software-DEFORMTM 3D. The characteristics of metal flow in different periods were analyzed, and the curve of variety in non-round area at different crosssections of the rolled piece, the curve of variety in bulge volume and the curve of variety in non-column volume were obtained. On this base the method of tool design is worked out and validated by experiment.
